Yesterday Tonis and I had a four hour XP session, the second one of a
series which will continue today. Yesterday we learned:

Google does not support CalDAV, therefore we decided to abandon#1201 (Lino as a calendar server).

The only really end-user friendly integratad solution would be to
write connectors to the leading proprietary APIs (Google, Apple,
Facebook, Microsoft…) in order to make Lino collaborate with these
systems. I am not currently willing to invest into such projects.

The only generic solution is therefore to work on the mobile
interface.

Before diving into a solution based on ExtJS modern (until now we
have classic), Tonis and I started to study whether the existing
bootstrap ui can evolve into a usable responsive read-write UI.

Concretely we started by removing
lino.core.site.Site.default_user from
lino_book.projects.bs3 and by reactivating the login
functionality around bootstrap3/base.html. I actualy once
started this a long time ago but abandoned for reasons I don’t
remember in detail.
At the end of the session Tonis and I agreed that it was definitively a very interesting exercise and that we would continue on this tomorrow.

Lino’s authenticate method doesn’t return a User instance. Which
indicates that it was a silly API and that Django is better. And
anyway it is time for #1329 (Use a bit more of Django’s
authentication). So we decided to dive even deeper into the
bogs. Lots of code changes:

Renamed User.profile to User.user_type because (1) Django complained
about it (after renaming users to auth) and (2) it had to be done some
day anyway.

Upgraded Django 1.9.13 to 1.11.2

Unfortunately we had to do a few changes to Django. Lino master
currently doesn’t work with an unpatched Django. We must present
these changes tomorrow to the Django community and submit a pull
request for https://code.djangoproject.com/ticket/20313

I checked in above changes because Hamza should see them (ext6 is
concerned). It is 9pm and I am ready for bed. But it is fantastic: I
got inv prep to pass on all projects! Yes, the test suites are still
mostly failing because we didn’t yet change “users” to “auth” in the
.rst files. But that’s for tomorrow.
